The other reason I see is that Tom Tom, in their wisdom, have made maps too big for their devices. So if you buy a map for western Europe, you can only pick one or two 'zones' to include. Fucked if I'm giving them 75 quid for that.

Just wanted to big this up - great app with responsive devs (recent update broke show notes for me, they fixed it in a few hours), worth the cash if you spend your life listening to bloody podcasts like me!
